Method for Coupling and Collaborating Multiple Flexible Display Devices

Users have access to several types of devices such as smart phones, tablets, laptops, and more. The screen sizes of smart phones are relatively small and display limited content. Multiple devices operate independently and cannot share displays for a common purpose.

One approach to collaborative screens is, when using a desktop or laptop computer, a single computer has connectivity to multiple displays, depending the video adapter and device driver capability. In this example, there is a common central processing unit (CPU) with additional displays. Another approach is a pullout flexible screen concept, which provides a second display for the mobile device, but is similar conceptually to the computer example above with a secondary display.

Using devices together normally has the devices loosely coupled, with a small gap between the devices. To facilitate contextual collaboration between screens, a method is needed to allow users to create a tight coupling of the devices, so that minimal applied force removes a gap.

The novel contribution presents a multi-device configuration, with no gap between devices, in order to create a larger display area. Each device has its own CPU and collaboration is in place to build a large content display area from multiple devices. The tightly coupled devices can perform in a collaborative way in order to use a larger screen area for any primary device (e.g., mobile phone). The simplest implementation combines two devices; however, the configuration is not limited to any set number.

The core components of the multi-device configuration include:

 Magnetic strips as part of the device or as an accessory; standards of thickness must be in place to enable seamless transition

 Standard Application Protocol Interfaces (APIs) for communicating amongst devices about font size and what portion of the content to display. There is one primary device talking to and controlling the screen through the operating systems of the other devices.

 Collaboration software

 Wireless power transmission system

 Network connectivity through Bluetooth or Wi-Fi is required for the collaboration of applications between devices

 Peer-to-peer communication between the devices may be required for the collaborative aspects of this invention

The configuration comprises a small flexible magnetic strip installed either internally or externally at the edge of the flexible display. It can be installed at the four edges or two edges as desired by the user. The magnetic strip can be continuous or discontinuous. (A user can install the flexible magnetic strips as a mobile device accessory if it is not already installed in the device.)
